Abstract

PURPOSE:To lower the height of each story of a building and to perform air conditioning effectively, by arranging the indoor unit and the outdoor unit of an air conditioner one in a ceiling and the other in a curtain wall. CONSTITUTION:In cooling, blowers 24, 44 and 58 are driven. Air in an indoor space 10 is sucked through a ventilating hole 26 in a blower unit 20 and inputted to an air path 30 of a window part 18 through a ventilating hole 28. As the result of the processing of the load of a window surface, the temperature of the air becomes high. The air enters a lower chamber 34 of a wall part 22 at the upper part of the window through a ventilating hole 37. The most part of the high-temperature air, which has entered the lower chamber 34, rises up and hits a separating plate 32. The air is guided into an indoor unit 56 as indoor circulating air. After the heat exchange, the air temperature is lowered. The air is sent to a ceiling duct 38 and returned into the room. Part of the contaminated air in the room flows into an upper chamber 42 through a communicating hole 52 and exhausted to the outside through an exhausting port 50. Fresh outer air is introduced to an outdoor unit 42 through an outer air inlet port 48. The most part of the air is directed and guided upward and returned to the outer air through a heat exchange coil 46 as heat radiating air. Part of the air is supplied to the indoor unit 56 through an inlet port 54 in exchanger for the exhausted air from the inside of the room.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to increase the indoor office space, reduce the building floor height, and significantly reduce the air conditioning machine room, and at the same time reduce the heat generated in the indoor perimeter zone and interior zone during cooling and heating operations It is characterized by being able to easily and economically handle the load and effectively achieve indoor air conditioning.
Related to air conditioners in buildings.

Conventionally, the central system and the individual unit system are widely known as air conditioning systems for general buildings. Shikaru,
The central system usually requires relatively long ducts from the air-conditioning machine room installed in one part of the building to the air-conditioned room, which requires a large amount of transport power and requires a large amount of energy during transport. heat loss is large. In addition, in a unit system in which small air conditioners such as fan coil units are installed in a distributed manner, there is a wall part near the glass window or outer wall that forms the boundary between the outdoors and the indoors, that is, a perimeter zone, and a part far from the wall, that is, the perimeter zone. Due to the difference in heat load characteristics between the interior zone and the interior zone, separate air conditioners are needed for the make-up zone and the interior zone, which not only increases equipment costs, but also causes the air from both zones to mix with each other indoors. Mixed loss of heat load occurs.

”: Another method is to install a small air conditioner on the waist wall of the outside wall and blow air directly. Although this method is economical, it cannot adequately deal with the difference in heat load characteristics between the meter zone and the interior zone when the depth of the room is large, and in addition, the airflow is limited to the depths of the room. There is a disadvantage that the indoor thermal environment is not favorable.

The applicant of the present invention has previously improved the shortcomings of these known air conditioning systems, and has aimed to reduce costs by simplifying the system while maintaining a good indoor environment, and has also improved the transport power. In order to save energy, the load on the window surface is handled by airflow along the window surface in the room, and
An air conditioner that utilizes the space above a window was developed, in which return air and outside air are cooled and heated by an air conditioner installed in the ceiling next to a window, and then returned to the room.
No. 8060).

However, this "air conditioner" eliminates the disadvantage that the air conditioner, which consists of a fan coil unit or heat pump unit, is all housed in the space under the ceiling, so the space under the ceiling needs to be raised, resulting in a high floor height. I could not do it.

Therefore, the present invention makes it possible to reduce the required floor height as much as possible by arranging the indoor unit part and the outdoor unit part of the air conditioner, one in the ceiling and the other in the curtain wall. It is. More specifically, the present invention integrally installs an outdoor unit section of an air conditioner and an indoor air distribution device section for window load processing in a curtain wall, and also installs an indoor unit section of the air conditioner. It is installed integrally within the transverse space so that it can be connected to the ceiling ventilation panel to form the indoor ceiling surface.

In this way, the purpose is to provide an air conditioner that has an overall cooling/heating/ventilation function and at the same time a heat isolation function from the outside air.A specific example will be described below.

In Figure 1, CL is the ceiling surface, FL is the floor surface, CL and F
The space between L and L is the indoor office space]0. The space ``0'' is blocked off from the outside by a curtain wall 12, and the curtain wall ``2'' is a glass 14 and a blind.
The waist wall section 20 includes a window section 18 consisting of a window section J8, a waist wall section 20 below the window section J8, and a window upper wall section 22 on one side of the window section J8. A blower 24 is housed, and ventilation openings 26 and 28 are provided in the lower part of the indoor side and the window side of the waist wall part 200, respectively, and the whole forms an indoor air circulation device part for window load treatment. However, this is what functions as a ventilation unit.

Glass 1 in the window part 18 is attached by a known method.
4 and the blind 16, a ventilation passage 3° is formed, and the ventilation opening 28 of the waist wall portion 2o communicates with the ventilation passage 30.

On the other hand, the window upper wall 22 is preferably divided into two upper and lower chambers by an inclined partition plate 32. A compressor 36 is accommodated in the lower chamber 34, and a ventilation passage 3 is provided on the lower surface of the chamber 34.
Further, this lower chamber 34 has an opening 40 leading to a ceiling air duct 38 provided in the ceiling surface of the indoor office space 10.
One chamber 42 is provided with a blower 44 and a heat exchange coil 46 of the outdoor unit. Further, in the lower part of the blower 44 and the upper part of the heat exchange coil 4G in the upper chamber 42, an outside air intake opening 48 and an exhaust opening 50 are provided, respectively, at locations facing the outdoors. There are some that function as outdoor units.

As shown in FIG. 3, a part of the partition plate 32 that divides the window upper wall 22 into an upper chamber 42 and a lower chamber 34 (the left end in the figure) is cut out, and the partition plate 32 is divided into an upper chamber 42 and a lower chamber 34. A communication hole 52 is formed so that the chambers 42, 34 communicate with each other. In addition, another part of the partition plate 32 (the right end in the figure) is cut out so that part of the outside air taken in from the outside air intake opening 48 can directly flow into the opening 4O. A transverse space 56 is provided between the ceiling air duct 38 and the opening 40 of the lower chamber 34, in which an inflow hole 54 is formed. A blower 58 and a heat exchange coil 60 of the indoor unit are housed within this space 56.

This transverse space 56 is open at the left and right ends in the figure, and after treating most of the airflow from the lower chamber 34 deflected by the partition plate 32 to a temperature of 1 m, it is sent to the indoor space 10 via the ceiling air duct 38. In the present invention, the ceiling ventilation duct 38, which functions as an indoor unit for sending air, and the transverse space 56 near the window constitute a ceiling ventilation panel.
It will be understood that the ventilation function for heating and cooling can be increased by configuring the outer and inner wall surfaces of the unit with a heat insulating material. When the unit of the present invention is used as a cooling device, a switch for operating the outdoor unit 42 and the indoor unit 56 is required. (not shown) to control the compressor 36 so that the heat exchange coil 46 in the outdoor unit 42 functions as a condenser, and the heat exchange coil 60 in the indoor unit 56 functions as an evaporator. Blower 24
．． 44 and 58, air in the indoor space 10 is sucked in from the ventilation port 26 of the blower unit 200 as indicated by an arrow 62. The indoor air sucked into the blower unit 20 enters the ventilation path 30 of the window section 18 from the ventilation amount 1'' 28 above it as shown by the arrow 64, and the load on the window surface is reduced within the ventilation path 30. As a result of the treatment, high-temperature air flows through the ventilation opening 37 as shown by arrow 06 into the lower chamber 34 of the window upper wall 22.
Most of the high-temperature air that has entered the lower chamber 34 rises there as shown by arrow 68 (Fig. 3), contacts the partition plate 32, and is released as indoor circulating air by arrow 7O. The user is guided into the indoor unit 56 as shown in FIG. Indoor unit 56
The high-temperature air inside the room undergoes heat exchange to become low-temperature, and is sent to the ceiling ventilation duct 38 as shown by arrow 72. After that, the air is guided to the back of the room via the duct 38, and then
4, it is returned to the room through an opening such as a slit.

In this way, cooling of the indoor space 10 is achieved.

After the indoor air contaminated with cigarette smoke enters the lower chamber, a portion of it flows into the upper chamber 42 through the communication hole 52 as shown by arrow 76, and enters the exhaust opening 5O as shown by arrow 78. and is discharged outdoors (Figure 3). On the other hand, fresh outside air is introduced into the outdoor unit 42 from the outside air intake 48 as indicated by an arrow 80, and then returned to the outside air. The water is replenished into the indoor unit 56 through the inflow hole 54 as shown by the arrow 84 without being interfered with by the water. In this way, ventilation of the room is achieved at the same time.

On the other hand, when using the device of the present invention as a heating device,
The heat exchange coil 46 of the outdoor unit 42 is adjusted to function as an evaporator, and the heat exchange coil 60 of the indoor unit 56 is adjusted to function as a condenser. As a result, heating of the room and ventilation of the room air can be achieved at the same time through air circulation similar to the case described above.

Of course, in this case, most of the outside air 82 taken in from the outside air intake opening 48 acts as heat-absorbing air.In this way, the present invention forms the outdoor unit and the indoor unit separately, Place only the indoor unit inside the ceiling,
The outdoor unit was placed inside the wall above the window, and the indoor air circulation system was placed inside the waist wall below the window. This allows air for heat release (absorption) to circulate inside the outdoor unit, and the air blown out from the indoor air distribution device, that is, the blower unit, rises along the window surface and is sucked into the upper wall of the window. Most of the air is exhausted to the indoor unit as circulating air, and some of it is exhausted to the outside through the outdoor unit. Further, circulating air and some fresh outside air flow into the indoor unit to cool (heat) the air, and these two units constitute a heat pump. Furthermore, the outer inner wall surfaces of the window upper wall portion and waist wall portion and the window surface have a heat insulating function. Therefore, the present invention can achieve air conditioning, heating, and ventilation functions in an energy-saving manner, and can improve the efficiency of construction work by producing and installing an air conditioner integrally with a curtain wall or ceiling panel.

In this way, the present invention solves the problem of the reduction of indoor office space due to the floor-standing unit type air conditioner installed near the exterior wall occupying the wall, and the problem of increase in floor height due to the tattoo type unit type air conditioner occupying the ceiling. At the same time, for example, the air for window load treatment shown in Japanese Patent Publication No. 58-10653 is sucked into the ceiling through an opening provided in the ceiling close to the top of the window, and flows through the duct in the ceiling, causing high temperatures in summer. This is a solution that all at once solves the problem of negative thermal effects on the room caused by low-temperature flow in winter.
